ELECTRIC CHANNELING-MACHINE.

Specification of LettersPatent. Patented luau. 7, 1916.

Application filed February 2, 1907; Serial No. 355,405.

To all whom it mag "concern 9 Be it known that I, 'lkLlER'l" BALL, a citizen of the United States,'residing' at Clarem'ont, in the county of Sullivan) and- State ofNew-Hampshi-re, have invented an Improvement in Electric Channeling-Machines, of which the following description, in connection with the accompanying drawings, is a specification. like letters on the drawings representing like parts.

This invention relates to pulsators preferably of the reciprocating type and herein represented as specifically applied to tool actuating motors and, associatedwith improvements in quarryingmachines, shown in the present embodiment of the invention as of the channeler type.

In order that the principles ofthe invention may be fully apparent I have disclosed a single type or embodiment thereof in the acc mpanying drawings; wherein- Figure 1 is a side elevation of a channeling machine embodying my invention; Fig. 2 is an end elevation thereof; and Fig. 3 is a view mainly in vertical central section of one form of pulsator and Working cylinder employed in this embodiment of the invention.

Referring mainly to Figs land 2 of the drawings, wherein a single type of the invention is illustrated, the quarrying body of the machine, herein represented as a channeler. is indicated at 1 and is supported upon suitable wheels 2 that mavrun upon tracks 3. Power may be applied'to said wheels in any desired manner as, for example, by

' means of a separate motor mounted upon the body of the machine, or powermay be applied from the main motor in any suitable manner.

In that type of my invention herein illustrated I have chosen to indicate a pulsator for operating the'working parts of the machine, although it is apparent that any suitable operating means may be used. In the form of pulsator employed, the fluid, which is preferably compressed air, is supplied to the cvlinder thereof upon opposite sides of its piston and from thence is forced to the working cylinder, the air passing in pulsations first from one side of the piston of the pulsator to one side of the piston of the working-cylinder and then from the opposite portion of. the p ulsator-to -th e opposite side of the piston of the Working cylinder. The piston of the'pulsator' may be operated in any appropriate-manner as by an elec trio motor. A typeof such pulsatcr is indicated in the drawin s at 4 and is herein shown (Figs. 1 and 23 as bolted or suitably secured to a swing plate 5 mounted upon the body in suitable bearings as 6, as indicated in Fig. 2, and held therein in any suitable manner as by Ushaped bolts 7.

It is desirable in channelers and other quarrying machines to alter the position of the too-lsas by movement thereof longitudinally of the machine and also by tilting or rocking the same. While any suitable means may be employed forth-e purpose, I have herein represented the-Working cylinder 8 having the piston rod 9, to which the cross head 10 and tools 11 are connected, as mounted upon the standard '12 herein represented as secured by bolts (not shown) passing through slots 13 in the swing plate 5 and preferably, and as herein shown, so-

curing the same upon the face opposite that to which the pulsator is connected. As represented in Fig. 1, the swing plate is p rovlded at different points along its length and preferably at or near the opposite ends thereof with bolt holes and slots so that the standard may be positioned as desired, as for' example, upon either side of the pulsato-r. In order to connect the pulsator and working cylindc'r,-fieXible'o-r jointed connections 1% and 15 are employed, herein shown as connecting adjacent sides of the pulsator. and the cylinder at top and bottom respectively. In order to permit a change of position of the'standard' and working cylinder 'totheopposite side ofthe pulsator from that represented in Fig. 1 without the employment of longer connections than those e pri esend-thr ad d--portions lT Tand suitably secured to the swing plate and the body and a central nut 19. It is apparent that any suitable adjusting means may be employed for this purpose.

For the purpose of adj ustably feeding the tools toward or from the work, I have herein indicated a screw 20 suitably secured to the plate 21 bolted to the top of the working cylinder 8 and passing through a suitable bearing in the standard 12. The screw 20 or other cylinder elevating means may be operated by hand or power, but herein for the purpose I have represented a gear 22 having .meshing therewith a pinion 23 rotated by a hand wheel 24 (Fig. 2). The feed screw 20 has threaded engagement with a nut held against longitudinal displacement in the overhead arch at the top of the standard,

the nut being keyed or otherwise fixedly secured to rotate with the gear 22 and thereby elevate or lower the screw with its attached parts.

The pulsator may be operated in any de-' sired manner. In Figs. 1 and 2 an electric motor 25 is represented as bolted directly to the swing plate 5. A gear 26 thereon meshes with a gear 27 upon crank shaft 28 connected by itman 29 to the trunk piston 30 (Fig. 3 and dotted lines Fig. 1) of the pulsator. Thereby the piston 31 (Fig. 3) of the pulsator may be reciprocated and the compressed fluid alternately forced to opposite ends of the working cylinder.

In order suitably to build up the air or other fluid in the pulsator any suitable means may be provided. Herein for the purpose is shown a compressor 32 bolted or otherwise suitably secured to the top plate 33 of the pulsator as by the bolts securing said plate to the motor. Mounted within the cylinder of the compressor is a piston 34 having a piston rod 35 passing through a stuffing box 36 and connected to the piston 31 of the ulsator. Any suitable fluid pressure connections between the compressor and the pulsator may be employed. Here n for the purpose is indicated a pressure inlet 37 at the upper portion of the compressor, having a valve 38 normally spring seated and provided with means such as a cam lever 39 for securing or looking the valve open. An outlet passage 40 leads from the upper end of the compressor to the upper end of the cylinder of the pulsator, said passage being controlled by a valve 41 normally spring pressed to its seat and having means such as a cam lever 42 for securing or looking the same open. In the form of pulsator and compressor described, the building up of the air is accomplished by the upward stroke of the piston 34 of the compressor, whereby the air is forced into the upper portion of the pulsator above the piston thereof. A fluid pressure connection 43 leads from the lower portion of th compressor cylinder t pulsator piston.

the lower portion of the pulsator and a safety valve 44 normally spring pressed to its seat is provided at any suitable point in the pulsator and is furnished with means, as cam lever 45, for locking the same open.

As previously stated the upper portion of the pulsator is joined by the connection 14 to the upper portion of the working cylinder as indicated at 46 (Fig. By means of an inlet port 47 pressure is admitted from said connection 14 to the upper side of the'piston 48 of the working cylinder. 1

It may be desirable to elevate the piston and thereby the cross head and drills without raising the working cylinder, as for adjustment or change of the tools. While I may employ any suitable means to that end. I have herein shown valved means whereby the fluid pressure entering through connection 14 may be introduced at the lower portion of the working cylinder below the piston 48 therein. instead of above the same. In this manner the working piston will be held elevated without interrupting the operation of the pulsator. To effect this result a valve 49 having the handle 49 is herein shown as rotatably mounted in the head plate of the working cylinder and is provided with a curved passage 50 adapted to be placed in communication as shown with the inlet port 47 or with a passage 51 leading to the working cylinder beneath the piston therein. .As'here shown the valve is provided with a vent 52 adapted to register with a vent 53 communieating with the upper portion of the working cylinder whereby when pressure is admitted by means of the passage 51 to the lower side of the piston 48, the pressure that has accumulated above said piston may be discharged. The valve 49 is herein shown as held in position by a suitable valve cap 54.

Viewing Fig. '3 it will beapparent that in the building up of the air in the pulsator air may be forced into the cylinder thereof below the piston 31 by placing the valve 49 in communication with the passage 51, so that ressure may pass from the upper end of the pulsator cylinder through the connection 14 past the valve 50 through the sup ply passage 51 to the lower portion of the working cylinder and thence by means of the connections 15 to the lower portion of the pulsator cylinder beneath the piston 31 therein.

As indicated in Fig. 3, the cross-sectional area of the compressor cylinder substantially equals that of the trunk piston 30 of th pulsator plus the cross sectional area of the compressor rod 35, so that the compressor piston 34 acting in conjunction with the piston 31 of the pulsator affords a balancing of pressure upon opposite sides of said Having thus described one type or embodiment of the invention, I desire it to be understood'that although specific terms are usedthey are employed in a generic and descriptive sense alone and not for purposes of limitation, the scope of the invention being set forth in th following claims.
